치경부 병소는 부적절한 칫솔질, 화학적 침식 및 차아의 굴곡 등의 여러 원인에 의해 크게 cervical abrasion, erosion 및 abfraction의 형태로 나타난다. 최근 노령 환자층의 증가와 치주 치료에 의한 구강내 치아 잔존율의 증가는 치경부 병소의 증가를 가져왔다. 이러한 치경부 병소는 지각과민증, 우식 및 심미적 이유 등으로 수복을 시행하며 구치부위에 작은 우식이 없는 치경부 병소가 있는 경우 환자에게서 지각과민증를 유발하지 않는 경우라면 수복을 시행하지 않을 수도 있지만, 많은 예에서 더 이상의 치아 및 치주 조직의 손상을 억제하고 치수의 보호를 위해서 수복을 시행한다. 특히 전치부의 경우에는 병소가 작고 우식에 이완되지 않았다 할지라도 그 심미적 측면 때문에 수복을 시행하는 예가 증가하고 있다.(중략)
Purpose: The purpose of this study was to analyze level of dental health knowledge and behavior in elementary student, school health educators should encourage students to have continuous dental care habits for lifelong dental health with practical education. Methods: The subjects in this study were 490 students of four-year, fifth-year and sixth-year from elementary school in Daegu areas. The data was collected through a structured questionnaire from 26, June to 27, June 2006. Collected data were analyzed into frequency and Chi-square test using Spss 10.0 program. Result: Level of dental health knowledge were high as 57.8% in high groups, dental health behavior were high as twice a day in toothbrushing, over three times in visiting frequency of dental clinic for one years and once time of a day in intake frequency of cariogenic food. dental health knowledge by an academic years and sex were significant difference all of four-year, fifth-year and sixth-year. dental health behavior by an academic years and sex were significant difference in visiting frequency of dental clinic for one years and in intake frequency of cariogenic food by an academic years, male and female were significant difference in toothbrushing of a day. relationships of dental health knowledge and behavior were significant difference in intake frequency of cariogenic food.
The purpose of the present study was to examine dental hygienists' perception of the current national practical examination. This research was performed using 199 self-reported surveys answered by professors of dental hygiene studies and clinical dental hygienist. Frequency analysis, chi-square tests, and analysis of variance were performed by using IBM SPSS Statistics ver. 20.0. The results revealed that many of the respondents consider the current national practical examination to be neutral. They did not think that the current national practical examination questions are useful for assessing occupation-centric integrated clinical practice ability and counseling techniques for patient intervention. The professors of dental hygiene studies believed that among the research tasks required as mentioned in the national practical examination questions, dental polishing and tooth brushing education are of paramount importance, whereas clinical dental hygienists believed that ultrasonic scaling is the most important (p<0.05). Most of the professors of dental hygiene studies reported that they conducted skills education for dental polishing and tooth brushing education, while most of the clinical dental hygienists reported that tasks actually performed in the clinic included impression taking, model fabrication, ultrasonic scaling, and explaining treatment precautions (p<0.05). Therefore, these tasks can be effectively carried out with the improvement of the national dental hygienist practical examination.
The findings of the study illustrated that the college students felt more stress when they had to receive treatment for the sake of oral health, and that they experienced less stress when they took good care of their oral health for preventive purposes. A self-administered survey was conducted on 235 junior college students whose majors were unrelated to health in the region of Jeollanam-do from March 4 to 30, 2015. A total of 27.2% of the respondents had received dental caries treatment, and 48.1% had received periodontal treatment. When the stress of the college students about personality, appearance, families and interpersonal relationship was measured, they were most stressed out about their personality ($3.40{\pm}0.73$). Specifically, they scored highest in the item "It's such a hassle to do something" ($3.73{\pm}1.20$), and scored lowest in the item "I was concerned about someone else's problem" ($2.22{\pm}1.15$). The female students experienced more stress about their appearance, personality, families and interpersonal relationship than the male students. The male students felt more stress about their studies than the female students. The college students who had dental caries and periodontal diseases suffered stress that was above the average level, and the stress level of the group that had scaling experience and/or had received toothbrushing education, namely taking care of oral health for preventive purposes, was more below average than the other group that didn't. In a word, it's urgently required to take measures to prevent college students from having oral diseases, as the students who suffered from oral diseases and received treatment were more stressed out. The implementation and revitalization of systemized educational programs are required to help college students stay away from oral diseases to promote their oral health.

The purpose of this study was to evaluate the tooth color changes of resin bonding sites and their adjacent sites on orthodontic bracket bonding. Sixty extracted sound premolars were used and the tooth color was recorded according to the CIE $L^*a^*b^*$ color system using a spectrophotometer. The tooth colors of the twenty premolars were measured and compared before bracket bonding and after removal. On a further twenty premolars, the tooth color was measured before and after only primer application. In the change of $L^*$ values, according to the bracket bonding and primer application, the lightness was decreased, and in the change of $a^*\;and\;b^*$ values, the color was changed into a more yellowish color The color differences $({\Delta}E^*)$ were calculated from the $L^*a^*b^*$ values and compared with the standard value of clinical detection $({\Delta}E^*=3.7)$. The color differences between before the bracket bonding and after removal noted exceeded the standard value and those of between before and after the primer application were not larger than the standard value. Toothbrushing was performed after application of the primer to evaluate the color changes according to the primer abrasion. As a control, toothbrushing was performed on the last twenty premolars. The color differences noted were larger than the standard value after toothbrushing. Also, to evaluate the color changes of the tooth which is exposed to sun irradiation after bracket removal, additional photoaging was performed and the color was measured for all teeth. The additional color differences after photoaging were smaller than the standard value. The above results suggest that the tooth color changes after fixed orthodontic treatment.
This study was executed from June first to 30th. 2005. The target was first and second graders of Bok-Hyun elementary school and their mothers. The total of participants was 275 persons and the component ratio was 135 first graders and 140 second graders, also 82 boys and 193 girls. They answered to the question sheet by writing out with their own hands. Among the 300 question sheets that were answered, 275 sheets were analyzed, excepting 25 sheets that got poor answer. The results were as follows; (1) About the behavior of mothers and their children for oral health, In mothers' case, 68.8% of them answered that they brush teeth more than 3 times a day and 31.3% answered that they brush teeth less than 2 times a day, so those who brush teeth more than 3 times were more than those who brush teeth less than 2 times In children's case, on the contrary, 14.2% of them answered that they brush teeth more than 3 times a day and 85.8% answered that they brush teeth less than 2 times a day, so those who brush teeth less than 2 times were more. (2) In 7 questions for researching mothers' knowledge level about fluorine, 55.3% of them answer 3~4 questions correctly. In 7 questions for researching mothers' knowledge level about Periodontal disease, 47.3% of them answer 3~4 questions correctly and it was highest. (3) In a case of the relation between oral health knowledge and behavior of mother and frequency of brushing teeth of children, statistical similarity on frequency of brushing teeth was shown(p < 0.05). (4) In a case of the relation between social-anthropological features of mother and frequency of brushing teeth of children, there was no statistical similarity on age, mothers' educational level, monthly income. However, statistical similarity was shown about existence of mothers' occupation(p < 0.05).
This study was conducted to provide basic data for improvement of the oral health management ability and the factors affecting oral health recognition and practice of 6th graders. The research subjects total 259 numbers of 6th grade students in two schools located in Changwon, it was investigated and analyzed with structured questionnaires. The collected data is analyzed by using IBM SPSS Statistics 19.0. The average oral health recognition score investigated were $3.19{\pm}0.41$, and $2.95{\pm}0.43$ for oral health practices. The oral health recognition was statistically significant differences by father's education (p<0.01), perceived oral health status (p<0.01), perceived grade (p<0.01), intention to attend oral health education (p<0.001). The oral health practices was statistically significant differences by father's education (p<0.01), perceived oral health status (p<0.001), perceived grade (p<0.05), parent's interest in child's toothbrushing (p<0.01), experience of oral health education (p<0.001), intention to attend oral health education (p<0.05). The factors that may improve the oral health recognition are in order of oral health practices, intention to attend oral health education, and parent's attention to child's tooth brushing. The factors that may improve the oral health practice was found to be in order of oral health recognition, parent's attention to child's tooth brushing, and perceived oral health status. As a result, in order to improve oral health management ability of 6th grade students, the surrounding environment, the attitude on oral care, the interest of oral, and the current disease status of oral health are required to be identified, then the oral health education program should be provided.
Of the many pathogenic Candida species, Candida albicans is the main fungal pathogen of humans. The oral environmental factors considered in the Candida albicans colony forming unit test contain both host and microbial factors associated with candidiasis. In particular, Candida biofilms can develop on surfaces of prosthesis. The purpose of this study was to investigate the distribution of oral Candida species between the type of prosthesis and the situation of oral environment in patient with prosthetic appliance. The patients were 30 elderly subjects with different types of prosthesis, 7 who wore denture, 12 who wore implant and 15 who wore removable orthodontic appliance. We used Candida albicans colony forming unit test using saliva to exam the distribution of Candida albicans related with 5 oral environmental factors, gender, smoking or nonsmoking, alcohol/nonalcohol consumption, the type of prosthetic appliance and its treatment duration as well as tooth brushing frequency per day. In conclusion, for the patient's gender, site in the oral cavity and the type of prosthetic appliance and its treatment duration was associated with an increase in the distribution of Candida albicans in saliva. The distribution of Candida albicans within the oral cavity performs to be modulated to varying extents by oral environmental factors and, further investigations are required to elucidate these complex interactions.
This study is trying to grasp the stress of the male high school students and the correlation between the stress according to the oral health important cognitive and self-rated oral health status and number of brushing, emphasizing the need for the education of oral health important, providing the basic data in order to accomplish correctly until the enhance of oral health-related quality of the oral health correct behavior. From May to July 2013, a self administered survey was conducted by the selected by convenience sampling from subjects of two high school located in Chungcheongnam-do 1, 2 grade. The SPSS PASW Statistics 18.0 and Amos 5.0 program had been used for the statistical data analysis. The study results were as follow: 1) Among five areas of stress, the stress of school life was the highest as 2.11 points and the stress of home problem was the lowest as 1.51 points; 2) The significance analysis results between the five areas of stress according to the stress of latent variable and the oral health-related quality of life all showed the significant difference (p<0.001). 3) Oral health-related quality of life was higher as oral health important and self-rated oral health status positive. Furthermore oral health-related quality of life was higher as number of brushing increased; 4) Fit Measures test result of stress, academic level, and family economic level model all showed more than 0.9 in goodness of fit index (GFI), adjusted GFI, normed fit index and root mean square residual and root mean square error of approximation values is all estimated less than 0.1, so it showed good model. From this study, it can be concluded that there is the correlation between stress and oral health-related quality of life.
